Safety cantilever crane cantilever crane detect what areas need to be developed in recent years, the production of advanced lifting equipment, compact, lightweight, easy to operate, wide application range, lifting capacity, economical and durable, get a lot of users of all ages. However, for safety reasons, it needs to be tested before use to test their operational performance is qualified, are generally to be detected at several projects. 1, compliance with the provisions of the design drawings and technical documents. 2, the electrical wiring is installed correctly, the motion controller is normal. 3, riveting, welding quality metal structure is good, the structure is of sufficient strength and stiffness. 4, each braking device, limiting device, the safety devices are reliable, action is sensitive and accurate. 5 agencies in the mechanical transmission is smooth and sounds normal. 6, electrical components at work temperature is normal. 7, centralized lubrication oil passage is smooth. Operation and inspection of equipment before the experiment. To protect the safety of running test, carried out smoothly, must be carefully checked for jib cranes crane equipment before the experiment, and fully prepared for the test well. Such as jib cranes lifting equipment in use, safety is the most important, the crane turntable, do not wait until an accident only to solve, Gongyi crane, preferably before use to detect good, be prepared to reduce accidents happen, hand crane operation safer. BZZ type jib crane is our combination of advanced technology developed its own heavy-duty jib crane. The machine has a lifting capacity, large working range, simple structure, easy operation and maintenance and so on. It has a variable cross-section column arm, slewing ring drive and electric hoist or hoist components. Jib crane through the base anchor bolts in the concrete foundation, driven by the motor and gear reducer drive gear together slewing ring slewing jib cranes rings, electric hoist or hoist to do the job to run back and forth on the sealing arm steel beams. In operation form, the user can choose to manually operate switches or wireless remote control. The product is widely used in metallurgy, shipbuilding, machinery, railway, garages, docks and other workplaces, to complete the bridge crane can not reach the work area.
